Adsorption of Vitamin C on a Fullerene Surface: DFT Studies
Density functional theory (DFT) calculations were performed to investigate adsorptions of vitamin C (Vit) on the surface a fullerene structure (Ful) in gaseous and water–solvated systems. Two models of Vit including OVit and MVit were created based on the original structure of Vit for OVit and methylation of all hydroxyl groups for MVit. All singular and hybrid structures were optimized and the...
متن کاملComputational studies on the interaction of vitamin C (ascorbic acid) with nitrogen modified TiO2 anatase nanoparticles
Density functional theory calculations were performed to investigate vitamin C interaction withN-doped TiO2 anatase nanoparticles. The adsorption of vitamin C on the energy favorable fivefoldcoordinated titanium sites was investigated. Various adsorption geometries of vitamin C towardsthe nanoparticle were examined. Since the adsorption energies of N-doped nanoparticles are higherthan those of ...
متن کاملLarge scale studies with vitamin C.
The combination of a regular daily supplement of vitamin C with extra dosage at the time of illness has been shown to reduce the disability due to common colds and other winter illness, but we have seen little effect on frequency of infections, sense of (well-being), or levels of serum cholesterol. The variable results that have been obtained from some other trials of vitamin C may be due in pa...
متن کاملVitamin C Intake, Circulating Vitamin C and Risk of Stroke: A Meta‐Analysis of Prospective Studies
BACKGROUND Though vitamin C supplementation has shown no observed effects on stroke prevention in several clinical trials, uncertainty remains as to whether long-term, low-dose intake influences the development of stroke among general populations. Furthermore, the association between circulating vitamin C and the risk of stroke is also unclear. For further clarification of these issues, we cond...
متن کاملMetadichol® Induced High Levels of Vitamin C: Case Studies
We recently reported that Metadichol® [1] brings about a three to four-fold increase in Vitamin C levels in patients without the use of Vitamin C supplementation. In this study of 6 patients who experienced a 5-12 fold increase in plasma Vitamin C levels higher than 80-100 u mol/L level which is the highest reported to date by oral supplementation at high doses of Vitamin C. Metadichol improved...
